i will get the ball rolling here, try to keep it neat and to the point guys!
group 1:
light/dark arts recast: this would be better if it added to the benefits/penalty for the respected arts such as 1% less mp 1% less cast/recast per merit
helix dmg: with the regen and helix changes, could we add regen into this merit as to boost both our "over time" spells?
mod verita: this JA still fails 99% of the time, till it is fixed this is worthless
sublimation: not sure what could be done for this, maybe increase the total amount restores from 10 per merit to 20? (...not really sure on this one, not a big fan of this merit)
group 2:
sotrmsurge: either boost the effect or add to it such as +1% atk boost per merit to firestorm or even adding to resist would be nice(example: 10 resist per stat gained, so firestorem with max merit = 70 fire res)...maybe even upping the stat to 2 per merit for total of 10 would be nice. Sad to say this is our best merit for group 2 so would not mind any improvements.
Enlightment: this is a useful ability, however it retains the penalty of the arts you are under, would like to see this fixed so you are given both light and dark art bonuses for the duration of this ability(which is one spell)
the other 4 stratagems merits: to be frank these are all very bad merits in my opinion. to start off drop needing 2 stratagems and make it 1. the -enmity stratagem doesn't even stack with our pax spell. The macc stratagem is fairly low. (someone else feel free to tackle these 4 merits, i rly think they need to completely redo these to be worth even considering)
(note: not sure refinement encompasses new merits for the category so i will refrain from adding any random ideas)
